I AIR-CURRENT DEFLECTDR- AND DUST COLLECTOR.

Application filed November 8, 1924-,Serial No. 748,603. Renewed June 21, 1928.

My invention relates to sanitary means for ventilation through windowand small openings, and the object thereof it to provide properly deflected currents of air to avoid injurious drafts and, at the same time, ineehanically to remove considerable portions of dust which may be carried by the air currents and prevent the same from entering the room. it is a further objectto provide a device primarily applicable to windows having sash of the vertically sliding or guillotine type, which can be rca dily and cheaply manufactured, including a secure fastening to hold the device in place, which can be compactly packed for storage and shipment, which as a whole can be easily applied to window openings of any desired or varying widths, which will not interfere with the operation of the sash, and which may be readily taken out and replaced for washing windows, for the removal of collected dust and for other desired. objects.

The principles of my invention are illustrated in the drawings in which Fig. 1 shows a perspective view of my invention, the parts being-disassembled but positioned in proper normal relation to each other; Fig. 2 is a sectional view of Fig. 1 on the line 22 when placed in operative relation to a window sill and sash; Figs. 3 and 4: show alternative sectional constructions of deflector members taken in the position of line 22 of Fig. 1.

For further description, referring to the drawings: Numerals 1 and 2 represent members made of thin sheet metal and forming a deflector as and for the purpose hereinafter set forth. The edges 3 and 4 of member 1 are turned toward each other to form a partial curve and the edges 5 and 6 of member 2 are also curved in like manner. The edges of the said members should have an easily sliding flt so that they can be moved longitudinally with reference to each other to close entirely or to be extended within the limit of secure overlap. End supporting brackets have the body portions 7 substantially in the form of elongated equilateral triangles. angles to the narrow or base edges and side flanges 9 and 10 are turned at substantially right angles to the side edges. They should be of the same construction and symmetrically formed throughout with reference to each other forn'iing substantial duplicates. Screw holes 11 and 12 may be placed in any convenient positions so that attachment may Top flanges 8 are turned at right be made at any desired point of a Window casing so that the recessed portions of the said brackets face each other. It will be ob served that the end flanges and the corre sponding side or lateral flanges should be slightly spaced from each other at 13 and 14.

The attachment of the device described to a window is illustrated in F 2 which shows the left hand bracket of F 1 attached to a stop 14, and so that flange 9 is extended toward the center of the window opening and in relation to the slidable lower window sash bar 15. The other bracket being attached in similar way to the other side of the window framing, the two members 1 and 2 forming the deflector are extended so that the lower edges thereof are received within the convergent portions of the lateral flanges and the upper portion of said. members are received Within the spaces between the ends of the latoral and top flanges thus rigidly securing the deflector in place.

It will be seen that, when so positioned, currents of air turned inwardly will impinge upon the faces of the deflector members and, when turned upwardly, any heavier materials such as dust or sand carried by the air currents will be deflected and their progress stayed at the under part of the detaining edge or flange t where they are freed from the air impulse, and left to settle to and be received by the lower curled flanges or receptacles 2 of the deflector. At this point, they are protected from any drafts of wind which would further scatter them and from this they may be readily removed by short ening the deflector to remove it from the brackets.

I have shown my invention with reference to deflector members having the edges formed in curved lines. They may be also bent in right lines as shown in Figs. 3 and 4, provided the overthrow is sufficient that the two members may be held in slidable relation.

It is further to be noted that, when the sect-ion shown at the lower part of Fig. 4 is used, a slight inward turn, as indicated at 16, should be provided to prevent the wind from blowing the particles of dust or sand out of the trough thus formed.

I claim:

An air current deflector and dust collector comprising a deflector plate having outwardly turned dust restraining flanges at its upper and lower edges, brackets for securing said deflector plate to a window frame at a predetermined angle to the perpendicular said brackets being of triangular formation, angle flanges at the edges thereof with the adjacent ends of the flanges spaced from each other, and said deflector plate having its ends received in the brackets with the lower dust restraining flange received between adjeacent angle flanges and the upper dust restraining flange disposed above the brackets with the ends of the deflector body received between and retained by the adjacent angle flanges.

In witness whereof I have hereunto set my hand at Chicago, lllinois, this 5th day of November, 1924:-

ROBERT E. BEAUBIEN.
